Description of the invention?) (Questions to be solved by the invention) In the above known UHF-VHF tuner, if it is necessary to construct the tuner wiring board 32 of the IC 31 for tuning, the circuit with the same function should be kept on the tuner wiring board 32 as much as possible, and as far as possible Shorten the connection wiring with the terminals 3 1: to 3 1 32 of the tuner IC 3 1 and arrange them so that they do not cross each other. However, the tuner IC 3 1 series VHF signal input terminal 3 13〇 and UHF signals The input terminals 3 131 and 3 132 are derived in the adjacent state, and the UHF switching terminal 3 123 is derived in the same manner as the FM notch connection terminal 3 124 and the VHF band switching terminals 3125 and 3126. Therefore, the UHF switching terminal 3 is connected. The control signals of 123 and UHF signal amplifying circuit 35 are cross-connected with the high-frequency signal wiring for connecting UHF signal dual-tuning circuit 36 and UHF signal input terminals 3 131, 3 132 and the dual-tuning circuit for VHF signal 40 and VHF No frequency signal input terminal of line 3 1 3D. At this time, since each high-frequency signal wiring is an impedance type line, and the control signal wiring is a low-impedance type line, when the two wirings cross, the high-frequency signal wiring is transmitted through the stray capacitance occurring at the crossing portion. Part of the high-frequency signal leaks to the control signal wiring side through the stray capacitance. While reducing the level of the high-frequency signal supplied to the mixing circuit, various obstructing signals or leakage voltage components overlapping the control signal wiring also pass through the stray. The capacitance is transmitted to the high-frequency signal wiring and mixed in the high-frequency signal, which becomes a problem that noise is output.
